Pachyrhizodus is probably represented from the Fort Pierre by 

 a fragment of a maxilla or dentary found by myself near Lisbon, 

 Kan., during the summer of 1898 ; the specimen is in a very 

 poor state of preservation, but bears a close resemblance to this 

 genus. Anogmius is represented from the Fort Benton by two 

 poorly preserved specimens, which were identified by Professor 

 Cope as Anogmius aratus. 



Next is given a table of genera of teleost fishes from the Up- 

 per Cretaceous deposits of Hakel and Sahel-Alma, in Syria, 

 Baumberge and Sendenhorst, in Westphalia, England, and the 

 United States.
